Cisco Connected Grid 8-Port RS-232 Serial WAN interface card

Legacy Protocol Transport

Utilities are migrating their substations from serial to Ethernet communications. Given the amount of serial communications in energy infrastructure today, the migration will take place over a number of years. The 8-port Async/Sync serial module in the Cisco CGR 2010 helps transport legacy SCADA (supervisory control and data acquisition) traffic across a TCP/IP network.

The serial interfaces provide a converged communications solution while energy infrastructure is migrated from serial-based Remote Terminal Units (RTUs) to Ethernet enabled RTUs and Intelligent Electronic Devices (IEDs). This supports network convergence andeliminates the need for costly separate leased lines for this traffic.
